NoN-REFILLABLE BOTTLE.

To all whom it may concern:

Be it known that I, JAMES H. QUINN, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented a new and useful Improvement in Non-Refillable Bottles, ofwhich the following is a specification.

This invention relates to a non-refillable bottle, and has for itsobject the overcoming of the defects common with many bottles popularlysupposed to be non-refillable bottles but which, in fact, can berefilled if submerged in a liquid in an inverted position. I avoid thesedifficulties by a double ball valve, one of said balls being of a lightmaterial and acting both as a valve and a float and the second being ofmetal and rolling freely upon the first mentioned ball when the bottleis in an upright position thus securely holding it to its seat andpreventing it from becoming unseated by pouring liquid into the bottlewhen in an upright position.

The invention consists essentially in a float valve, a ball Weightcoperating with said float valve and a suitable retaining device forholding the balls.

In the accompanying drawings, Figure l is a sectional view through theneck of a'bottle and through my device, the balls being shown inelevation and in the position occupied when the bottle is in' an uprightposition. Fig. 2 is a similar view showing the position occupied by theballs when the bottle is gently decanted. Fig. 3 is a detail perspectiveview of the retaining cage removed from the bottle, and Fig. 4 is asection on the line 4-4 of Fig. l.

In the drawings A represents the upper portion of a bottle having anelongated neck portion A/ slightly contracted in its lower portion andprovided with an annular roll A2 adjacent its upper end above which acork or stopper of any kind not shown can be inserted. The retainingdevice consists of a cylinder B having a lower truncated conical portionB upon which is fitted a rubber collar O which wedges into thecontracted portion of the bottle neck and thus preventing the passage ofany liquid from or into the bottle between the sides of the bottle neckand the retaining device. The cylinder B is held in the neck of thebottle against withdrawal by two angle spring arms D which are securedto the sides of the cylinder and which spring outwardly as their angleportions pass the shoulder A2 and engage the said shoulder. To prevent CSpecification of Letters Patent.

any tampering with the valves by the insertion of a wire or otherinstrument a suitable valve cage E having a slotted top portion and-side openings is secured in the upper portion of the cylinder B, andthe free ends of the spring arms D project into and rest beneath the topof said cage, thereby preventing their being engaged by a hook orgripping device and drawn upwardly for the purpose of disengaging themfrom the shoulder A2. The valves are further held in place by two crossbars F arranged one above the other and at right angles to each other,these bars extending diametrically across the cylinder B. I also placewithin the cylinder B a tapering sleeve G with its smaller end downwardand the upper end portion longitudinally slit. The sleeve is of a springmetal and its lower portion is of less diameter exteriorly than theinterior diameter of the cylinder B while the diameter of its upperportion is slightly greater. By forming it of spring metal and slittingthe upper portion, it can be readily forced into the cylinder B and thelower portion will stand out spaced from the sides 'of said cylinder asshown in the drawings. The lower edge of this sleeve acts as a stop forone of the ball valves as will hereafter appear.

Within the conical ortion of the cylinder B, I place a light woo enfloat valve H which when seated in the lower end ofthe retaining deviceseals the same. I also place in the retaining device a heavy ball I,preferably of metal which normally rests upon the light or float valve Hthus holding it firmly to its seat. When the bottle is to be emptied itis decanted and the two balls drop into the position shown in Fig. 2thus permitting passage of liquid around them. If, however, any attemptis made to refill the bottle by submerging it, in an inverted position,the entrance of any liquid into the retaining device will float thelight ball H lifting it to its seat and any pressure exerted in aneffort to force liquid into the bottle will only cause the said ball Hto seat itself more firmly at the conical end of the portion B of thecylinder B.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. The combination with a bottle having an interiorly recessed neckportion, of a cylinder fitting in said neck ortion, said cylinder havinga lower conicall portion, a spring metal sleeve fitting within the upperportion llO of the cylinder, the lower portion of said sleeve being ofless diameter than the interior diameter of the cylinder, the lowerportion of the sleeve being spaced from the cylinder walls, a floatvalve arranged in the lower ortion of the cylinder, a weight valve normaly resting on the float valve, the said weight valve being spherical inshape and engaging the lower end of the sleeve, said sleeve forming asto for said weight valve, means carried by the cylinder for locking thesame in the bottle neck, and means carried by the cylinder to preventtampering with the said valves,

2. The combination with a bottle, of a cylinder having a conicalcontracted lower poriloat ball resting loosely in the contracted lowerend of the cylinder, and a metal ball resting upon the first mentionedball, and eni gaging the smaller end of the sleeve when the bottle isdecanted.
